Electron configuration for an element gives an idea about distribution of electrons in atomic orbitals. Let us study the electron configuration in below steps.
The Electron configuration of Nobelium is [Rn] 5f14 7s2. Nobelium (No) has atomic number 102 and is prepared synthetically in the particle accelerators. It is a radioactive, f block element which is the 10th transuranic element. The known isotopes of Nobelium to exist are thirteen.
In the following article, the Electron configuration, rules required for describing electron configuration and orbital diagrams for Nobelium will be elaborated step by step.
How to write Nobelium electron configuration?
The electron configuration of No is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 . The electron configuration is derived using the following steps illustrated below:
- s orbital can hold up to 2 electrons.
- p orbital can hold up to 6 electrons
- d orbital can hold up to 10 electrons, and
- f orbital can hold up to 14 electrons.
- The electrons are filled in the respective shells using Aufbau’s principle, Hund’s rule and Pauli’s exclusion principle.
- Thus, the electron configuration of No is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 .

Ground state Nobelium orbital diagram
The ground state orbital diagram for No is drawn using the following steps:
- At first, with respect to increasing order of energies arrange the orbitals.
- The electrons are then filled in the orbitals as per Aufbau’s principle, Hund’s rule and Pauli’s exclusion principle. The ground state orbital diagram of No representing the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 is illustrated as follows:
Conclusion:
The electron configuration is very necessary to obtain information about an element’s magnetic property and oxidation state. Nobelium was found to behave as the heaviest homolog of ytterbium. Nobelium is only used for research purposes.
